CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS SATURATQR Application filed October 30, 1929. Serial No. 403,401.

This invention relates to saturators, such as are employed in the manufacture of prepared roofing and the like, and has for its primary object to provide an improved form of gate rol ide frame for use in connection therewit which will remedy defects in existing structures.

Other and further objects and advantages will become apparent as the disclosure proceeds and the description is read in conjunction with the accompanying drawings, in which Fig. 1 is a longitudinal, sectional view of a saturant tank;

Fig. 2 is a plan view, partly in section and artly in elevation, of the saturant tank and rame; and

Fig. 3 is a sectional view taken on the line 3-3 of Fi 2.

One of tfie steps .in the manufacture of preared roofing, weather roof sheeting, insuatin pa er, and the li e, consists in passmg the oun ation sheet, which is to form the basis of the desired roduct, through a tank containing a hot as altic compound or saturant. To insure t orough impregnation, it is customary to pass the foundation sheet through the saturant a number of times which is accom lished by providing a series of upper loop orming rolls above the level of the saturant, and a series of lower loop forming rolls, commonly known in the art as gate rolls, adjacent the bottom of the saturant tank. To facilitate threading the foundation sheet through the loop forming rolls, the gate rolls are usually adapted to be raised by a suitable hoisting mechanism to the level of the upper rolls thus permitting the rolls to be threaded without the necessity of removing the saturantfrom the tank.

The upright members employed to guide the gate rolls in their vertical travel have usually heretofore been riveted in one way or another to the side walls of the saturant tank, but such practice has met with difiiculty due to warping and buckling of the walls of the tank brought about by the high temperature of the contained material. As a consequence, the guide members are often distorted and the normal operation of the gate rolls is greatly interfe'redwith.

Referring now to the drawings, the reference character refers to a saturant tank located below the floor line 11. The tank ma be of any suitable sha e and is provided with a marginal flange 12 a ong its u per edge. A series of upper loop forming rol s 13 are journaled in suitable bearings preferably near the I squeeze rolls are preferably power driven in unison, as is usual in such constructions.

The gate rolls 14 are preferably formed from pipe sections 18 and are provided with plu s 19 which carry an axial shaft 20 extending beyond the ends of the pipe section to form trunnions. These trunnions are journaled in bearing blocks 21 to which are secured angle uide members 22 having their transverse we s spaced from the block to form guide pockets. Rods 24, secured at their lower ends to the bearing blocks 21, extend u wardly parallel to the sides of the tank and are suitably joined at their upper ends to threaded hoisting rods 25. Hoisting mechanism, generally designated 26,.cooperates with the threaded rods 25 to raise the gate rolls 14 to any desired adjustment and permits a ready threading of the foundation sheet through the series of upper and lower rolls when the latterare raised to a position above the level of the saturant.

The hoisting mechanism 26 may be of any suitable form and ishere illustrated as operating through a train of gears 27, 28, 29 and 30 to raise and lower the gate rolls as desired.

Suspended from the flanged walls 12 of the saturant tank 10 is a guide frame generally designated 31 which cooperates with the angle member 22 and bearing block 21 to maintain the gate rolls in proper alinement ment.

and to guide them in their vertical travel. The outside dimensions of the guide frame 31 are somewhat less than the inside dimensions of the saturant tank so as to allow the frame} to be freely suspended within the tank. The guide frame 31 comprises angle bars 32 which rest upon and are secured. in any suitable manner to the flanged walls 12 of the saturant tank. The horizontal web of the angle bar 32 is of sufficient breadth as to space the vertical web of the bar away from the side walls" of the tank. Upright guide members 33, preferably in the form of angle bars, are secured to the bars 32, as byv riveting,the lower ends of which extend downwardly to a point adjacent the bottom of the tank. Horizontal, longitudinal beams 34 and 35 and transverse beams 36 and 37 are secured v to the lower ends of the upright members 33, and with suitable cross braces 38 form a rigid frame member. 7 A

The transverse webs of the upright members 33 extend into the pockets formed between the transverse webs of the angle members 22 and the blocks 21 to guide the gate rolls when they are moved vertically and to maintain the said rolls in proper ahnement.

Means are advantageously provided for adjusting the frame 31 with reference to the side walls of the tank. These means may take the form of spacer or adjusting bolts 39 provided adjacent the ends of the horizontal beams 34, 35, 36 and 37, and are provided with lock nuts 40 to maintain the adjust- The nuts 41 which are welded to the vertical webs of the horizontal beams 34, 35,

'36 and 37, is but an expeditious way of furpractically unaffected by any warping or buckling of the said walls. In any event, such warping or buckling will not distort or injure the upright guide members 33, and' should the lower portion of the frame 31 be moved from its adjusted position through contact of the walls of the tank with the frame 31 by the adjusting bolts 39, it is but an easy matter to bring the frame back to its proper position.

It is apparent that the invention may 'be embodied in other specific forms without departing from the spirit or essential attributes thereof, and the present embodiment of the invention is to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims, rather than to the foregoing description, to indicate the scope of the invention.
